DELIVERY MECHANISM FOR COMMODITIES.

machines, having more particular reference to delivery mechanisms forcommodities and has for a primary object the provision ofa mechanism ofthis character which is comparatively simple and capable of holding andejecting the articles in an eilicient manner. A further object is toprovide ejecting mechanism of novel construction.

"ith the above and other objects in view to be referred to asmydescription progresses, my invention resides in the features ofconstruction, arrangements and combinations of parts hereinafterdescribed and succinctly defined in my annexed claims.

Referring to the accompanying drawing wherein like numerals of referenceindicate like parts throughout: Figure 1 is a view partially in sideelevation. the casing being broken away. Fig. 2 is a herizontal'sectionthereof. Fig. 3 is a fragmentary detail of the ejecting mechanism forone of the compartments, the same being illustrated as in operation.Fig. 4 illustrates the same mechanism. the view being taken at rightangles to Fig. 3 and portions of the guide being broken away, and Fig. 5is a vertical transverse section taken on line 5--5 of Fig. 2. a

Referring to the drawing by numerals of reference, 1 indicates areceptacle ha ing a compartment 2 for suitable commodities, as 3.Con'ipartnxrnt is bounded by a horizontal partition i, and verticalguide members or standards the latter being fixed to the top and bottomwalls of receptacle 1 and connected by a cross-guide 6' depending fromthe rear edge of a delivery slot 7 of receptacle 1, so as to normallyact with guide members 5 to engage and hold the foremost article 3 inposition for delivery by suitable mechanism to be described.

Reference numeral 8 indicates an external hood of receptacle 1 extendingover slot 7 and serving to turn and direct the articles during theirdelivery movement. Partition 4 forms a support for the articles, whichlatter are advanced toward guide members Specification of LettersPatent.

5 by a follower 9, this being slidably mounted on partition at andconnected with weights 10 by flexible connections 11 taking oversuitable sheaves 12.

' The ejecting mechanism comprises spaced slides 13, guided for verticalmovement on guide members 5, and provided with article engaging teeth14:. A series of these teeth is provided on each slide, the componentteeth of a series consisting of slender pins normally inclined upwardlytoward the article to be ejected and having their upper pointed endsresting thereagainst. Teeth 14: are fixed, as by screws '15, to carriers16, pivotally mounted, at 17, on slide 13 and having their outer endportions weighted, so that the carriers are normally operated by gravityto hold the teeth 14 in their upper or inactive positions, againstsuitable stops 18. Other stops 19 limit the downward swinging movementof the teeth, as will be later understood.

I prefer to mount the teeth 14 in grooves -or seats of the carriers,which are overlapped by the heads of screws 15, to thereby firmly holdthe teeth. This structure, hov-qever, can be changed or modified withoutdeparting from the spirit of my invention. it beinq understood that theobiect so ght in this construction is to permit of the teeth being adusted from time to time as may be required to compensate for wearing oftheir active end portions. As now considered slides 13 are connected toguide members 5 by headed studs 20 slidably engaged in slots 21 of suchmembers.

- Reference numeral indicates a rock shaft journaled in the side wallsof receptacle 1 and having one end projecting and provided with a crankarm 23. lVithin the receptacle, shaft 22 is provided with arms; 24 whichare pivotally connected by linksor rods 25 to the adiacent slides 13.

In the operation of the mechanism thus far described. the operatorgrasps crank 23 and moves the same upwardly. During the initial portionof this movement, teeth 14 swing toward their stops 19 and embed theirpoints in the article, following which the article will be liftedthrough slot 7 where it can begrasped by the operator and completclywithdrawn. Follower 9 new advances the supply of articles and during theresetting or the return of the ejecting mechanism to its normalposition, teeth 14 will ride freely over and without injury tothe nextarticle to be ejected.

10. ments' being provided with a division Wall;

30, a bottom partition consisting of spaced members 31, and uprights 32,E114. latter defining the rear boundaries of the compartments 2', 2 andbeing formed integral with members'3l. The magazines or other similararticles are arranged in superposed relation in compartment 2/,2 andwill consequently lower by gravity following'the ejection of one oftheir number.

'The ejecting mechanism for compartment 2, --2" being identical inconstruction a description of one willsuffice. This comprises apairof'slides 33 slidably-connected with -members 31 byheaded pins34c-engagingin slots 35 thereof, as shown. Theseslides are formed withshoulders 36 which normally lie at the rear side of the compartment toengage the adjacent edge portion of the article, as shown in Fig. 1.Advance move- "ment of the slides will therefore force-thearticlethrough a delivery slot 7', normally I closed by a hinged closure8. Slides 33 are 'pivotally connected by links or rods 36 with arms 37of rock shaft 38. The rock shafts 38 have their inner end portionstelescoped, and thereby supported at such'ends for relative rotarymovement. Their outer end portions projectthrough the adjacentreceptacle walls and are provided with crankarms, as 40.

Various changes can be made in the details of construction as fallwithin the scope of my annexed claims.

Having thus described my invention What I claim as new, and desire tosecure by Letters Patent of the United States of America, 1s

1. A device of the character described comprising a support forarticles,.a movably mounted ejecting device, spaced stops on saidmovable device, and a movably mounted article engaging tooth projectingbetween the spaced stops and adapted to engage an article 'for removingthe same by movement of the ejecting device, said tooth being limited bythe stops and independently movable of the ejecting device.

2. A device of the character descr bed comprising a casing provided witha delivery opening, means in said casing for supporting articlessidebyside, reciprocatory means for e ecting the articles from said comprisinga support for the articles, an

ejecting device supported at one end portion of said support formovement at an angle thereto, 'pivotally mounted carriers on saiddevice, article engaging teeth mounted on said carriers for adjustmentlengthwise thereof, said carriers being normally yieldingly held to-holdtheir teeth in engagement with the article to be removed and an anupwardly inclined position, and means for reciprocating said device.

1 "-4. A device of the character described eomprising a support for thearticles, an ejecting device'supported atone end portion of said supportfor movement at an angle thereto, spaced and independently movablecarriers on said device arranged one in advance of the other, articleengaging teeth mounted on said carriers, said carriers being gravityoperated to normally hold said teeth inclined upwardly, stepson theeject,- ing devices for limitingswinging of said carriers in either'-'direct1on, and means for movingsaid device.

'5. A device of the'character described comprising a supportforarticles, a movably mounted ejecting device, spaced stops on thedevice, a -movably mounted article engaging tooth carried on the deviceand projecting between the spaced stops, and means tending to move thetooth to an inoperative position, one of said stops limiting themovement of the tooth by said means, the other of said stops beingadapted to hold the tooth in an operative position for engaging one of 1the supported articles.

6. In a device of the characterdescribed, comprising a support for thearticles, an ejecting device supported adjacent tosaid support formovement at an angle thereto,

spaced and independently movable carriers on said device arranged one inadvance of the other, article engaging teeth mounted on said carriers,stop means for limiting swing ing of said carriers in either direction,and means for moving said device.
